Title: Plasma arc torch and method using contact starting system
Inventor: LU ZHIPENG
IPC: H05H1/34
Filed: 1997-09-17
Granted: 2002-07-02
Abstract: Disclosed is a novel method and structure for contact starting a plasma arc torch. A translatable, electrically conductive component such as a nozzle or swirl ring is biased into contact with an electrode by a compliant spring element. A pilot arc is formed by first passing current through the electrode/component interface. Thereafter, the component is translated under the influence of gas pressure in a plasma chamber formed between the electrode and component, compressing the compliant element and initiating the pilot arc. The spring element may be a separate element o r may be maintained integrally with the nozzle, swirl ring, or a retaining cap , facilitating removal and replacement of the spring element with consumable components of the torch.

Granted: 2003-10-21
Abstract: The present invention provides a method for interpreting shear-wave seismic data to detect fractures in the subsurface of the earths crust. Seismic shear waves are acquired along medium symmetry planes and their corresponding AVO intercepts and gradients are estimated. The resulting AVO attributes are combined using a weighted least squares solution to estimate the change in splitting parameter and fast shear velocity, which are diagnostic of the presence of fractures. The method is also useful in assessing the porosity of the subsurface. Knowledge o.f subsurface fracturing and porosity is useful in locating, for example, oil and gas wells.

Title: Process for the preparation of high activity carbon monoxide hydrogenation catalysts; the catalyst compositions, and their use
Inventor: CULROSS CLAUDE C
IPC: C07C1/04
Filed: 1998-07-10
Granted: 2006-09-12
Abstract: A process for the preparation of a novel highly active, highly selective catalyst useful for conducting carbon monoxide hydrogenation reactions, particularly Fischer-Tropsch reactions, the catalyst per se, and process for use of such catalyst in conducting carbon monoxide hydrogenation reactions, particularly Fischer-Tropsch synthesis reactions. T he catalyst is prepared by contacting together, preferably by dispersing in a liquid, a preformed, particulate refractory inorganic oxide support, preferably a fumed silica support, compound or salt of a catalytic metal, or metals, i.e., a metal selected from Groups IB, IIB, VIIB or VIII of the Periodic Table, preferably cobalt, an oxidizable alcohol, oxidizable aldehyde, or oxidizable ketone promoter, suitably glyoxa l, and an oxidant sufficient to react with the promoter and convert the metal, or metals, to an insoluble highly dispersed metal carboxylate which is deposited and supported on the support. The solids are recovered, and heated at an elevated temperature to reduce the catalytic metal, or metals, to the zero-valent state and form the catalyst composite. This catalyst in its reduced form is very active, and selective, in conducting carbon monoxide hydrogenation reactions, particularly in converting a mixture of hydrogen and carbon monoxide to C5+ hydrocarbons, on contact of the gaseous mixture with the catalyst at reaction conditions.

Abstract: A method for manufacturing reduced iron agglomerates comprises the steps of supplying iron oxide agglomerates including carbonaceous material on a moving hearth, heating and reducing the agglomerates to yield reduced iron agglomerates while the moving hearth moves in the reduction furnace, discharging the reduced iron agglomerates from the reduction furnace, recovering the reduced iron agglomerates, and removing seized hearth fragments separated from the moving hearth in close proximity to a discharge location or a recovery location for the reduced iron while the reduction furnace is being operated. According to the method, the reduction furnace can be operated for a long period of time without stopping the operation thereof and supply of the iron oxide agglomerates. Consequently, high productivity of the reduced iron agglomerates can be achieved, and in addition, superior quality in high degree of metallization of the reduced iron agglomerates can be obtained since the seized hearth fragments having low degree of metallization are not mixed with the reduced iron agglomerates as a product.
